While SG-1 and Jack O'Neill attends the extraction ceremony of the last Goa'uld System Lord. Ba'al comes up with an ominous warning, he explains he has a contingency plan in the event something like this ever happened. In the meantime, the real Ba'al travels back in time to 1939, to create an alternate timeline in which Earth never found their Stargate. He then, using the knowledge gained in the original timeline, takes control of the Goa'uld Empire.
